Robertson said there were limitations in tracking success on narrow measures such as gdp growth.

Speaking to reporters after his speech, alongside Prime Minister Jacinda Ardern, Robertson said all New Zealanders understood that the country had not done enough over a long period of time to make sure that mental wellbeing was of the highest standard.
Robertson's speech was followed by youth panel chaired by Prime Minister Jacinda Ardern, some of who talked about the mental health pressures on youth today.
